Hello,

the link for the sitemap that you reported is correct and also the sitemap is ok, just checked in the browser.
However it's the link for the image sitemap, the first operation to do would be submit the regular XML sitemap, in your case:
http://albirms.com/index.php?option=com_jmap&view=sitemap&format=xml&lang=nl

Of course if you are using Google or Bing webmasters tools it's just enough submitting this link probably you are right, only notice that using for example Google webmasters tools only the final part of the links is needed: index.php?option=com_jmap&view=sitemap&format=xml&lang=nl

If you get some weird errors such as that the sitemap doesn't contain URLs, it's likely that there is some other problems.
The first thought is about ensuring that bots are allowed to fetch the sitemap.

Greetings,

John Dagelmore
